You need a tubular driveshaft. 33/34 are best, I have used 32 4 cylinder shafts.

You cut the rear end off and weld in a 10 spline to 6 spline coupler. Not sure if some lathe work is needed, I've never had that combo of parts to use. In my case I used 32 4 cyl shafts, a normal 6 spline coupler, and because the 6 spline coupler is smaller diameter than the 10 to 6 adaptor coupler, and the 32 shaft is shorter than the 33/34, I turned up a short adaptor sleeve to get me where I needed to be.

You then shorten the torque tube to match, eliminating the centre bearing at the same time.

Alignment of all the parts is hyper critical and cannot be taken for granted.

Misalignment will lead to premature wear of the couplers and pinion splines and locking pin breakage. I know this from experience.

I have read that the original 10 to 6 spline couplers are better quality than the repro parts available.

The late and much missed Dick Spadaro used to supply brand new driveshaft kits emulating the setup described above.
